looking ffmpeg [documetation page](https://trac.ffmpeg.org/wiki/Encode/VP9) all
about convert to webm which we are looking into.
Some notes from IRC chat:
- If your film was recorded with 25 FPS and you're encoding with 100 FPS (see
status line at the bottom from ffmpeg conversion) then it will be done in 4
times faster than real time. If encoding at less than 25 FPS, then it will go
slower than real time.
- The FPS that you can encode is determined by your CPU power. GPUs can be used
but a random person on IRC tells me that better results are seen whilst using
CPUs.
It also seems to be possible to use [HandBrake](https://handbrake.fr/) although
it's unclear where the options in the menu are for doing the conversion.
